The number of words in the master's thesis is relatively small, generally about 25,000 words is enough, and it can be a little more, but it is not recommended to be less.
Of course, there is no rigid requirement for this number of words, but it depends on whether the content of the paper is complete and the logic is sufficient. It doesn't matter if all the words meet the standard.
I am an example myself. Due to the advice of experts, nearly 20,000 words were deleted, and the final graduation thesis was less than 30,000 words, but the content was standardized and complete and passed smoothly.
